Good Gawd. That makes the Cummins Killer Dowel Pin look like a minor inconvenience.
Most diesel manufacturers these days are moving toward rear-geartrain engines (European designs) for emissions purposes... so this sort of thing will only become more common. Now that the Cummins engines in Dodge trucks have gone to the rear geartrain design, a lifter failure will also require engine removal and major disassembly (though not QUITE as major as in the case of this Powerstroke).
Similar issues with Mercedes and Volvo truck engines. Can't say about GM/Isuzu... but I suspect they're no better from a serviceability standpoint.
